Integrating VirusTotal in your Browser

Sometime you open a webpage or an infected file and the antivirus still silent, without alerting about any suspicious activity on your machine, this is maybe due to not having the latest AV signature or that the malware are encrypted to make the AV not recognize it or that the file is clean and do not contain any malware.

The first thing I do if I have a suspicious file or webpage is to scan it on Virustotal , The benefit from this step is to check the file with more than 40 different antiviruses. Now there is a new service that adds the possibilities to scan files or webpages directly from the browser on Google Chrome and Mozilla Firefox.

VTzilla is a Mozilla Firefox browser plugin that simplifies the process of scanning Internet resources with VirusTotal. It allows you to download files directly with VirusTotal’s web application prior to storing them in your PC. Moreover, it will not only scan files, but also URLs.

The scanning options are embedded in Firefox’s context menu and download dialog, making the analysis process as easy as clicking a single button.

VTchromizer is a Google Chrome browser extension that simplifies the process of scanning Internet resources with VirusTotal. It allows you to scan links (including links to files) directly with VirusTotal’s web application. It will scan the submitted URLs with the URL analysis tools and the file downloaded from the site with VirusTotal’s antvirus solutions.

Unlike VTzilla, VTchromizer does not embed itself in the browser’s download dialog, only in the context menu. Google Chrome still does not offer an API to modify the download dialog, having said this, you can still scan any files that you want to download by right-clicking on the links to those files and choosing the “Scan with VirusTotal” option.
